A foundation named after former Chicago Bear Dave Duerson, who committed suicide last year, donated 80 concussion kits on Friday to football programs at Chicago public high schools.

“It is our hope and duty to contribute to a safer game of football in memory of my father,” said Duerson’s son, Tregg, in a news release.

Duerson’s family is suing the NFL because they believe the organization hid information that showed concussions from playing football cause brain damage.

The lawsuit alleges Duerson, who also played for the New York Giants and Phoenix Cardinals, sustained at least three concussions during his 11-year NFL career.

Chicago Public Schools coaches and football staff can screen athletes for concussions or head injuries using the kits, which employ something called the King-Devick Test. The results help them decide if the players should be pulled from the game.

The district requires its coaches and athletic directors to undergo concussion management training to better identify head injuries, according to the statement. The training also provides criteria for removing players from games.

In August 2011, CPS enacted a policy that keeps student-athletes with concussion-like symptoms off the field until a physician or certified athletic trainer says they can return. If neither is available, the student must receive medical care at a facility.

The Dave Duerson Foundation plans to work with CPS and the King-Devick manufacturer to ensure at least one person on every football team is trained to use the kits. The tests will be passed out to all 80 of CPS’ high school football programs in the near future.
